Abstract

Today, modern power system carries very high demand from the load side. Thus, they cause the stability problem. This paper investigates the problem related to the voltage stability in the power system and controlling the power flow through transmission line using a FACT controller known as Static Synchronous Series Compensator (SSSC). In this paper, the FACT controller investigates the effects for controlling the active and reactive power as well as damping power system oscillation that occur because of the heavy loaded system. Under heavy loaded conditions, there may be insufficient reactive power causing the voltage to drop. This voltage may lead to drop in voltage at various buses. Flexible AC Transmission System (FACTS) controller have been mainly used for various power system stability. In this paper, the authors used a Pulse Oscillation Damping controller with SSSC to damp out the system oscillation and maintain the stability of the power system. The SSSC equipped with source of energy in dc link can supply or absorb the active power to or from the line along with the reactive power flow control. The SSSC is represented by a variable voltage injection with associated transformer leakage reactance and voltage source.
